Druing his first visit to Laos, President Obama announced Tuesday that the U.S. would provide an additional $90 million over the next three years to help Laos clear unexploded ordnance that has killed or injured more than 20,000 people.

The U.S. bombardment dropped more than 2 million tons of ordnance on the small nation, more than "we dropped on Germany and Japan, combined, in all of World War II," Obama said.

The U.S. bombings were part of a CIA-run, secret operation aimed at destroying the North Vietnamese supply routes along the Ho Chi Minh trail and wiping out its communist allies.

They also left a trail of devastation in Laos, which U.S. planes used as a dumping ground for bombs when their original target was unavailable and planes couldn't land with explosives.
